Conventionally available IGBTs with 1700 V blocking voltage are designed for the requirements of motor control application in 690 VAC networks where DC-link voltage is typically about 970 V and maximum below 1200 V. For renewable applications, higher DClink voltage is required going up to 1500 V which is the limit of the low voltage directive (2014/35/EU). Hence, a new 2.0 kV class IGBT in the LV100 housing has been developed and evaluated under the requirements of renewable applications such...

Enepaq to firma produkująca moduły baterii zlokalizowana w Wilnie na Litwie. Moduły baterii Enepaq mogą być stosowane w szerokim zakresie zastosowań, ale od samego początku i pierwsze moduły baterii zostały zaprojektowane specjalnie dla zespołów Formula SAE, aby stać się prawdziwymi liderami w wyścigach formuły elektrycznej, i w rezultacie Enepaq jest znany jako dostawca modułów baterii dla Formula Student.

The demands have grown on EMC know-how in modern product development. ICs today are much more sensitive and the number of EMC standards and directives which have to be complied with has risen too. This article deals with the possibilities open to an electronics' developer nowadays to optimise devices and circuits in terms of EMC.

Imagine for a moment that you are trying out a brand new car: you slide into one of the ergonomic seats, start the engine and, to make things perfect, would like to listen to some music. But when you switch this on, you suddenly notice interesting side effects. The light comes on in the passenger compartment, for example. Or the radio starts whistling and whimpering.

Complex devices with integrated circuits and a low supply voltage increasingly fail interference immunity tests. The localisation and elimination of weak points is a real challenge in such complex devices. The fast, specific and hence cost-saving elimination of weak points requires effective strategies and appropriate equipment for systematic immunity analysis on the board level.

If you are using fluorescent lighting in hazardous areas then you need to take actions right now.

Pressure sensors are an essential element of automation of ventilation systems. These sensors are designed to measure air or gas pressure and provide accurate readings to the control system. Automation of ventilation systems is becoming more and more important in modern buildings because it allows better control of air quality and energy efficiency. Pressure sensors are used to monitor pressure in channels, pipes and other elements of the ventilation system. They can detect pressure changes...

Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it will double a previously announced its investment plan to approximately 260 billion yen in the five-year period to March 2026 mainly for constructing a new wafer plant to increase production of silicon carbide (SiC) power semiconductors.

Using a patented switching technique, Pulsiv has developed an entirely new method for converting AC to DC that delivers a combination of game changing benefits in power electronics designs. Our unique technology has extended the range of conventional flyback topologies to replace expensive LLC solutions, whilst achieving an unrivalled efficiency profile.

Suwnice pomostowe i bramowe są niezbędne, aby przemieszczanie ciężkich materiałów było wydajne, skuteczne i bez szkody dla personelu. Podczas produkcji cementu ciężkie elementy wyposażenia, jak również gotowe prefabrykaty wymagają transportu do obszarów magazynowych i/lub ciężarówek w celu dystrybucji.

Komórka produkcyjna prefabrykowanych bloków betonowych i płytek stwarza wiele zagrożeń dla pracowników i sprzętu. Sprzęt pod napięciem, maszyny obrotowe, piły i przecinarki przemysłowe, punkty zakleszczenia oraz punkty dostępu częściowego i/lub całego ciała stwarzają możliwość urazów kończyn. Zapewnienie przestrzegania właściwej kolejności czynności związanych z bezpieczeństwem zmniejszy ryzyko obrażeń.

Concrete is the most common used man-made material on earth. The uses of concrete range from structural applications to piping, drains, and pavers. Buildings, bridges, roads, and more could not be constructed without this important material.

Τhe storage of aggregate for various usage can lead to the potential risk to personnel involving engulfment within hoppers (confined space) and loss of materials due to incorrect materials loading. Protecting workers from confined space hazards that can occur during maintenance, cleaning, filling, and unloading of hoppers is critical within a gravel pit.

Czujnik firmy DOL to idealne rozwiązanie do budynków inwentarskich. Przemyślana metoda 3 w 1 mierzy zarówno pomiar wilgotności względnej, temperatury jak i dwutlenku węgla (CO2). Inteligentne rozwiązanie ułatwia instalację czujnika, ogranicza jego konserwację do minimum, a więc jest on po prostu bardziej opłacalny. Czujnik DOL 139 został zaprojektowany tak, aby wytrzymywać szczególnie trudne warunki w budynkach inwentarskich oraz środowiskach przemysłowych. Jego solidna obudowa i starannie...

Majoritatea metodelor de localizare a undelor de defect se bazează pe analiza curentului de linie transformat de transformatoarele de curent și sunt limitate la rețelele de înaltă tensiune. Localizarea undelor de defect în rețelele de medie tensiune este încă în curs de dezvoltare. Această lucrare prezintă un nou algoritm în timp real pentru identificarea undelor care călătoresc într-o rețea de distribuție utilizând semnalul de tensiune și metoda creionului cu matrice de scurtă durată. Pentru...

Steel components are used in a wide range of different applications, and are subject to heavy stress due to environmental influences and the effects of climate change. Specialised coating systems provide essential corrosion protection, but must be inspected regularly. Precise and robust measuring gauges and clear documentation are essential when conducting these inspections.
